I've been running a website for 8 years. We still have great visits, but our eCPM has been dropping monthly for years now. Ads are also becoming increasingly bloated, leading to slower and slower load-times for the website.
Back in December I switched from "http" to "https", unaware that doing so would rule out a few of my ad networks who don't support https. As a result, our revenue dropped 80%.
Anyway... I don't know what to do at this point. For those curious, the site is www.indieshuffle.com -- and right now we're serving ~600,000 ad impressions a day with a ~20% fill at... roughly $0.10 eCPM. Would love to know if you have any tips or suggestions.
